Pain is the most common symptom of sinusitis. You have several different sinuses above and below your eyes as well as behind your nose. Any of these can hurt when you have a sinus infection. Inflammation and swelling cause your sinuses to ache with a dull pressure. You may feel pain in your forehead, on either side of your nose, in your upper jaws and teeth, or between your eyes. This may lead to a headache (see below).
Sinusitis is inflammation and swelling of the lining membranes of the sinuses. This is commonly caused by bacterial or viral infections or blockage of the sinus openings by thickened mucosa called polyps. Symptoms of sinusitis include facial pain or pressure, nasal obstruction, discolored nasal drainage, loss of sense of smell, and headaches. The majority of patients with sinusitis can successfully be treated with antibiotics or other medications, treatment of allergies or environmental control.
